Specification of Letters Patent.

To all whom it may concern:

Be it known that I, CHARLES A. WHITE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Sheet-Delivery Attachments for Printing-Presses, of which the following is a specification.

This invention relates to sheet delivering attachments for bed and cylinder printing presses of that type known as two revolution front delivery presses in which the impression is made during one revolution of the impression cylinder and the advance movement of the reciprocating bed, and the printed sheet is removed from the cylinder and discharged from the press during the next revolution of the cylinder in the same direction and the return movement ofthe bed, the sheet passing out of the press in the same direction in which it is fed to the press. In these presses, as ordinarily constructed, the oscillating .fiy takes the printed sheets from traveling delivery tapes and piles them on a receiving table at the delivery end of the press. On account of the location of this receiving table over the inking mechanism,

only space enough for a comparatively low pile of sheets is afforded between the table and the fly and consequently it is necessary to frequently stop the press to remove the printed sheets.

The primary objects of this invention-are to produce a sheet delivering attachment which can be applied to the ordinary two revolution front delivery presses at small eX- pense and without material change in the press, and which is adapted to deliver the printed sheets onto a receiving table or device that can be lowered as the pile of sheets increases in height, so as to maintain the ,top of the pile at substantially the same height and permit a large pile of sheets to accumulate before the pile has to be removed; and also to provide elevating means whereby a wheeled table or truck can be raised to a position to receive the sheets directly from the fly and can be lowered as the pile increases in height until it rests on the floor, when it can be drawn away with the pile of sheets thereon and replaced by another receiving'table or truck, so as to obviate the labor of lifting the sheets in taking them from the press.

In the accompanying drawings, consisting of three sheets: Figure 1 is a fragmentary elevation of one side of atwo revolution front delivery printing press provided with a sheet delivery attachment and receiving table or device embodying the invention. Fig. 2 is an elevation of the opposite side thereof. Fig. 3 is a plan view thereof. Fig. 4 is a longitudinal sectional elevation thereof. Fig. 5 is a transverse sec tional elevation thereof in line 5-5, Fig. 4. Fig. 6 is a sectional elevation, on an enlarged scale, of the means for evening the pile of sheets on the receiving table or device.

Like reference characters refer to like parts in the several figures.

A represents the frame, B the impression cylinder, G the reciprocating bed and D, (Z, d the lnk applying and spreading rolls of a two-revolution front delivery printing press.

E represents the usual traveling delivery tapes which carry the printed sheets from the impression cylinder and from which the oscillating fly takes the sheets and piles them on the receiving table. Ordinarily this fly is journaled on the frame at the point indicated at f in Figs. 1, 2 and 4, to oscillate from a position between the delivery tapes E to a position over the receiving table f, indicated by dotted lines, Fig. 4, which is located over the inking rolls D, but in providing the attachment constituting this invention the fly G is removed from this location and is journaled at the extreme front end of the press on brackets H which are provided for the purpose and are secured to the opposite sides of the press frame, and an auxiliary set of tapes I is supplied for carrying the sheets from the main tapes to the fly G The fly may be oscillated in the usual way by a segment gear g, Fig. 2, on its shaft meshing with a toothed rack bar 9 which is reciprocated by-a cam g and spring 9 it being only necessary to provide a rack bar of suitable length to reach the fly in its new position at the end of the press. The auxiliary tapes I pass around wheels on the shaft 2' for the front ends of the main tapes and on a shaft 2" journaled in the brackets H, the auxiliary tapes being driven by the main tapes, which latter are driven by the usual gearing The auxiliary tapes are desirable in that they allow more time for the ink to dry before the sheetsare piled by the fly.

K represents a vertically movable table or device which is arranged at the front or delivery end of the press in position to receive the sheets directly from the fly' Gr. Preferably the receiving table or device consists of a wheeled truck which. is removably supported by elevating supports L on which the truck rests, see particularly Fig. 5. These elevating supports are movable vertically on stands M of suitable construction arranged at opposite ends of'the truck, and are movedfor raising and lowering the truck by ver-' tical screws N which are journaled in the stands M and work in screw-threaded holes in the elevating supports L. The supports have guide parts engaging the stands M to hold the s'upports from being-turned'by the screws N. The screws N can be turned by hand wheels it connected to the screws by bevel gear wheels n, orby other suitable means;

In the operation of the press the truckK is placed between the stands'M with the elevating supports L extending beneath the ends ofthetruck, and the screws N are operated'to lift the truck to asuitable height toreceive the printed sheets from the fly G. The fly operates to pile the sheetson the truck K'and the truck is lowered from time to. time as the pile of sheets increases in height, so as to maintain thetop of the pile at a substantially constant level suitable to receive the sheets from the fly. When the truck has been lowered far enough to rest upon the floor, one of theelevating stands M is moved out of the way'and the truck can then be wheeled away with thepile ofsheets, and-another truck put in its place and raised to the proper height to receive the sheets. In this way the press can make a long run, for instance, a whole daysrun, before it is necessary to remove the sheets, and the sheets do not have to be lifted or handled in-taking them fromthe press, so that a great deal of "time and laborare saved in operating the press.

The wheeled, trucks of ordinary construction to as desired without interfering with the operation of the press or requiring each truck to be equipped with its own elevating-means."

Any other suitable means could be employed for thus raising and lowering'the truck, and,

if preferred, an ordinary paper tray could described elevating means enables be used on the truck and raised off of and lowered onto the truck by the elevating means instead of raising and lowering the truck itself. o

0, Figs. 4 and 6, represents a device which is preferably provided for shifting the sheets asthey are delivered to the receiving table,

to keep. the pile even. This device consists of a rock shaft provided with fingers to strike the sheets and journaled in arms 39 clamped on a cross rod 7) connecting the brackets H. The shaft of the evening de-.
